Inki,

I still do not see the DTS tag [1] merged in your tree but you applied
patches breaking the display. I looked at exynos-drm-next branch.

We talked already about bisectability and with Hoegeun we provided
proper solution. Hoegeun split the patchset and I sent you a stable
tag to merge. Be aware not to apply the DTS patch because you would
effectively duplicate it. Instead, deal like with any pull request -
merge the tag as dependency *before* applying DRM DSI patch.

I saw also a branch like this:
https://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git/log/?h=exynos-drm-next-tm2
but this is something obviously wrong. I do not know what are your
plans to do with it, but please drop it as it brings only confusion.

Best regards,
Krzysztof
